I just got a Mini (not the Glo) for my commute; it's just the right size for my purse. The Glo's that I saw at Indigo on display looked very good! Having just gotten a new light and case for my T1, I just couldn't justify buying a Glo though...
The Glo works on the same software as the Mini and I must say that so far I like the reading experience on my Mini very much! Have read 2 books on it in the 3 days since I got it!
